MoonLake Immunotherapeutics, a clinical-stage biotechnology company, has emerged as a frontrunner in the pursuit of next-level therapies for inflammatory skin and joint diseases. With a singular focus on developing its proprietary Nanobody® technology, MoonLake is poised to transform the treatment landscape and address the unmet needs of millions suffering from conditions like hidradenitis suppurativa (HS) and psoriatic arthritis (PsA).
Business Overview and History
Incorporated in 2021, MoonLake Immunotherapeutics was founded with the ambitious goal of harnessing the power of Nanobodies to create innovative, targeted therapies. The company's primary focus is on the development of its lead product candidate, Sonelokimab (SLK), a novel tri-specific IL-17A and IL-17F inhibiting Nanobody.
In a significant move that shaped the company's trajectory, MoonLake AG, the Swiss subsidiary of MoonLake Immunotherapeutics, entered into an in-licensing agreement with Merck Healthcare KGaA, Darmstadt, Germany (MHKDG) in April 2021. This agreement allowed MoonLake to exclusively license and acquire the Sonelokimab program. The transaction was accounted for as an asset acquisition, with the majority of the fair value of the gross assets acquired relating to the in-process research and development of Sonelokimab.
Despite facing challenges typical of early-stage biotechnology companies, including significant losses since inception and the need to carefully manage cash resources, MoonLake has made substantial progress in its clinical development programs. The company successfully navigated the challenges posed by the COVID-19 pandemic, adapting its clinical trial protocols and procedures to ensure the safety of patients and staff while continuing the development of Sonelokimab.
The company's lead candidate, sonelokimab (SLK), is a tri-specific IL-17A and IL-17F inhibiting Nanobody that has shown promising results in multiple clinical trials. In May 2022, MoonLake initiated a Phase 2b trial of SLK in patients with moderate-to-severe HS, the MIRA trial, which met its primary endpoint of Hidradenitis Suppurativa Clinical Response (HiSCR) 75.00 in June 2023. Buoyed by this success, the company announced positive 24-week top-line results in October 2023, demonstrating further improvements in HiSCR75 response rates and other clinically relevant outcomes.
Building on this momentum, in February 2024, MoonLake announced the successful outcome of its end-of-Phase 2 interactions with both the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA), receiving unanimous support for its proposed approach to advancing the Phase 3 program of SLK in HS. The company subsequently initiated the Phase 3 VELA program in May 2024, with the first patients now enrolled.
Concurrent with the HS program, MoonLake has also made significant strides in PsA. In December 2022, the company initiated a Phase 2b trial in patients with active PsA, the ARGO trial, which met its primary endpoint of American College of Rheumatology (ACR) 50.00 in November 2023. The positive 24-week data from the ARGO trial, presented in March 2024, showed that continued treatment with SLK led to significant improvements across all key outcomes, including unprecedented multi-domain responses across joints, skin, and other domains.
Following the successful end-of-Phase 2 interactions with the FDA and EMA in June 2024, MoonLake announced the imminent commencement of the Phase 3 IZAR program in PsA, designed to further evaluate the potential of SLK in this indication.
Beyond HS and PsA, MoonLake has also outlined plans to initiate additional Phase 3 and Phase 2 clinical trials of SLK in juvenile HS, palmoplantar pustulosis (PPP), and axial spondyloarthritis (axSpA) around the end of 2024. This comprehensive clinical program underscores the company's commitment to addressing the diverse needs of patients suffering from inflammatory diseases.
Financials and Liquidity
As of September 30, 2024, MoonLake reported $375.66 million in cash and cash equivalents, along with $118.27 million in short-term marketable debt securities, totaling $493.93 million in available liquidity. This robust financial position is expected to support the company's ambitious clinical development roadmap and provide a cash runway through the end of 2026.
For the nine months ended September 30, 2024, MoonLake reported a net loss of $74.85 million, primarily driven by increased research and development expenses of $72.41 million, as the company advanced its clinical trials and expanded its pipeline. General and administrative expenses for the same period were $21.10 million, reflecting the company's investments in organizational growth and public company compliance.
Despite the lack of revenue generation, as MoonLake continues to focus on the development of its lead candidate, SLK, the company's strong cash position and strategic allocation of resources position it well to navigate the road ahead.
For the most recent fiscal year (2023), MoonLake reported no revenue, a net loss of $36,007,260, operating cash flow (OCF) of -$42,778,167, and free cash flow (FCF) of -$43,062,801. In the most recent quarter (Q3 2024), the company again reported no revenue, with a net loss of $35,930,212, OCF of -$25,274,811, and FCF of -$25,407,002. The decrease in OCF and FCF compared to the prior year was primarily due to increased research and development expenses related to the advancement of the company's clinical programs, particularly the Phase 3 trials for SLK in hidradenitis suppurativa and psoriatic arthritis.
MoonLake's liquidity position remains strong, with a debt-to-equity ratio of 0, reflecting the absence of outstanding debt. The company's current ratio and quick ratio both stand at 25.51, indicating a robust ability to meet short-term obligations.
To bolster its financial position, MoonLake has successfully raised capital through various equity offerings. In the three months ended March 31, 2024, the company sold 914,830 Class A Ordinary Shares under its at-the-market (ATM) program, generating net proceeds of approximately $52.50 million.
Product Segments and Geographic Markets
MoonLake is currently a single-asset company, with SLK as its sole product candidate. The company is developing SLK for the treatment of various inflammatory skin and joint diseases, including hidradenitis suppurativa (HS), psoriatic arthritis (PsA), axial spondyloarthritis (axSpA), palmoplantar pustulosis (PPP), and psoriasis (PsO).
SLK is a proprietary Nanobody that was previously studied by Merck Healthcare KGaA, Darmstadt, Germany (MHKDG) and Avillion LLP. Nanobodies are antibody-derived therapeutic proteins that offer potential advantages over traditional monoclonal antibodies, such as enhanced tissue penetration, easier manufacturing, and higher thermostability.
